Earth bulge formula
Webwhere r is the actual earth radius and R e is the effective earth radius. Commonly, the effective earth radius factor, k, is chosen as 4/3.However, at long ranges and with shallow angles, k can deviate greatly from the 4/3. (With no atmospheric refraction, k = 1. An infinite value for k represents a flat Earth). ). The effearthradius function provides two methods … WebOct 8, 2011 · Because gravity is pointing more towards the equator in an ellipse than a circle, the bulge on a spinning ellipsoid has to be a little greater. So you get a higher value: 3/2 w^2 r^2/g. Then I argued that most of the mass of the Earth however is at its center anyways, so you take the average: w^2r^2/g.
